Storage capacity at ANY photo site is one thing. Bandwidth (how much they are viewed) is another.
Fototime Bandwidth policy
Fototime allocates 5 times the amount of bandwidth as the storage capacity (Ex: 4gb storage = 20gb bandwidth.) This is cleared and zero'd out every 30 days. At the END of a month cycle is when the potential for problems may arise.
I do not use Photobucket, but if you search, I am certain that's in their fine print, too. If you have a basic Photobucket account, then the sand ran out of the hourglass.
Last year after Blade, I had to up my storage to
increase my bandwidth capacity. Fototime just downsizes to 640 wide when they run dry. You have a reserve tank, so to speak.
